Abstract: 1485839 Remote control of radio and TV receivers; semi-conductor pulse generators INTERNATIONAL STANDARD ELECTRIC CORP 12 Nov 1974 [17 Nov 1973] 48857/74 Addition to 1472451 Headings H3Q and H3T [Also in Division G4] In an ultrasonic transmitter for remotely controlling radio and TV receivers, a source of direct voltage U2 is connected via a booster diode D2, a tapping of a coil L1 and a further diode D1 to provide a polarizing voltage across the parallel connection of a controllable electronic switch T1 and on electrostatic ultrasonic transducer W, an end a 1  of the coil is connected through a booster capacitor C1 to the pole of the source to which the booster diode is connected such that the booster diode and capacitor boost the voltage supply 1, 2 across the transducer. As shown the transducer is periodically short circuited in rhythm with the ultrasonic frequency to be radiated by a transistor T1 or thyristor which is driven by a control generator such as a switchable frequency divider circuit which is supplied from a crystal controlled generator. During the first switch on phase, only the part a 2 -a 3  of L1 stores energy, which during the subsequently following blocking phase, remains to be stored to a small extent as a polarization potential on the capacitance Cw of the transducer W, until being dissipated by the next switch-on phase. The resonant voltage appearing during the blocking phase at the coil L1 and its capacitances, is rectified by the booster diode D2 and stored as a booster voltage in the booster capacitor Cl. For further switching phases both the voltage source U2 and the booster voltage U3 serve as the supply voltage 1, 2 of the circuit. Circuit ports or modules such as the module generating the switching pulses to T1 requiring a supply voltage which is higher than the source U2 can be connected across 1, 2.
